HYDRAULIC RAM.

SPECIFICATION forming part of Letters Patent No. 337,112, dated March 2, 1886.

(No model.)

To aZZ whom, it may concern:

Be it known that I, ADoLPHUs BAER, a citizen of the Republic of Switzerland, residing at Zurich, in Switzerland, have invented certain new and useful Improvements in Hydraulic Rams, of which the following is a specilication, reference being had to the accompanying drawings, which form a part of the specification, and in whichi Figure l is a longitudinalv vertical sectional view of my improved hydraulic ram, taken on lines M N, Figs. 2 and 3. Fig. 2 is an end view of the'same; and Fig. 3 is a top view of the rain, showing the air-chamber removed and showing portions taken in section ou line PQ, Fig. 2.

Similar letters of reference indicate correponding parts in all the iigures.

My in ventiou has relation to hydraulic rams; and it consists in the improved construction and combination of parts of a ram having means for adjusting the stroke of the discharge and outlet valves, and having means for adjusting the tension of the discharge-valve, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the air-chamber, which is provided with the outlet pipe a, and which is secured by suitable clamps and by a suitable packed joint upon the water-chamber B, into which the feed-pipe enters at one end. A valve-seat, d, having au outwardly projecting guideframe, C, is suitably clamped upon a'ange, e, at the discharge end of the water-chamber, and the discharge or stop valve c plays upon the inner i'ace of this seat. The guide-frame consists of side pieces, f, the end pieces of which are respectively formed with a smooth bearing, g, near the valve seat, and with a screw-threaded bearing, g', at the outer end of the frame, and the stemt' of the dischargevalve slides in the inner bearing, g. A screwthreaded sleeve, h, projecting inward from a disk, h', having a series of notches in its edge, iits in the screw-threaded bearing g', and has the outer end of the discharge-valve stern sliding in it, and the notches in the edge of the disk are engaged by a pawl or latch, k, pivoted at its inner end to the end piece ofthe guideframe. The outer end of the valve-stem is Kformed with a collar, Z, which bears against the notched disk, and it will be seen that the iuward stroke of the valve and valve-stem will be regulated by adjusting the screw-threaded j sleeve and its disk in the female-threaded 5 5 bearing in the end of the frame, the stem sliding in the inner bearing in the frame and in the sleeve. An outer disk, m', and an inner disk, m, slide upon the valve-stern and confine a spiraly spring, a, which is wrapped around 6o the stem and bears with its ends against the grooved and dang-ed inner faces of the disks, and the outer disk bears against the iunerend of the screw-threaded sleeve, while the inner vofa nut and litsjamnut o, which fit upon theKA stein, which at that portion is screw-threaded. It will be seen that the tension of the spring which furnishes resistance for the dischargevalve against the fiow of water may be regulated lov means of the nuts upon the threaded portion ofthe valve-stem. The upper side of the water-chamber is provided with a valveseat and aperture having a cross-bar formed with a vertical bearing, c, and a valve, b, having an elastic disk, r, secured to its under side, plays upon this seat, being clamped upon .the valve-stem t between a disk, s, bearing against the elastic disk and held upon the stern by the lower portion ofthe stem being enlarged, and a nut, a, which ts upon a threaded portion of the upper end of the stem. s The upper end of the stem slides in a vertical bearing,1, formed at the top of a yoke, y; projecting into the air-chamber, and an adjusting-nut, u', and ajam-nut, ai, serve t'olimit the upward stroke of the valve and stem, the adjusting-nut stopping against the bearing in the yoke when the valve is raised, and the jam-nut bearing against the lower end of the adjusting-nut. In this manner it will be seen that the flow of water into the air-chamber, and consequently out through the outlet-pipe, may be regulated, and the resistance of the discharge or stop valve may be regulated, as well as its stroke, regulating the force with which the water will enter the air-chamber and rise in the outlet-pipe, as well as the volume ofthe same, by regulating the volume of water flowing out of the discharge-aperture roo before the same is closed and the water repelled and forced through the outlet-valve.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a hydraulic ram, the combination of a water-chamber, a valve-seat secured at the discharge end of the chamber and having au outwardly-projecting guide-frame formed with an inner smooth l/angitudinal bearing and an outer screw-threaded longitudinal bearing, a discharge or stop valve having a stem passing through the bearings, and having a collar secured at its outer end, a screw-threaded sleeve tting in the threaded bearing and having a notched disk at its outer end, the stem sliding in the sleeve with its disk bear-ing against the outside ofthe disk, and a latch pivoted to the end of the guide-frame and engaging the notched disk, as and for the purpose shown 'and set forth.

2. In ahydraulic ram, the combination of a water-chamber, a valveseat secured at its discharge end, and having an outwardlypro- Y jecting frame provided with a smooth longitudinal inner bearing at one end and a screwthreaded bearing at its outer end, a screwthreaded sleeve fitting in the threaded bearing and having a disk with a notched edge at its out erend, a pivoted latch engaging the notched edge of the disk, a discharge or stop valve playing upon the seat and having a stem sliding in the bearing and sleeve, and formed with a collar at its outer end and with a screwthreaded inner portion, a disk upon the stem bearing against the inner end of the threaded sleeve, a disk fitting upon the inner portion of the stem, adj usting-nuts bearing against the inner face of the disk and fitting upon the threaded portion of the stem, and a spiral spring wrapped around the stem and held between the disks, as and for the purpose shown and set forth.

3. In a hydraulic ram, the combination of a Water chamber having a valve-seat at its upper side formed with a central bearing, an air-chamber having an outlet and secured over the valve-seat, a stem sliding with its enlarged lower portion in the bearing of the seat and having a threaded middle portion, a yoke having a bearing in its upper portion for the upper end ofthe stem, a valve upon the stem having an elastic disk clamped between a disk upon the shoulder and aunt upon the th readed portion of the stein, and a stop-nut and a jamnut upon the threaded portion of thestem, as and for the purpose shown and set forth.

In testimony whereof I hereunto sign my name, in the presence of two subscribing witnesses, this 14th day of November, 1885.

. ADOLPHUS BAER.
